ELBRIDGE F. BARNES AND LORENZO O. STRIOKLAND, OF NEW HAVEN, CONNECTICUT.

OUTSIDE PlPE CUTTER.

SPECIFICATION forming part of Letters Patent No. 301,080, dated July 1,1884.

Application filed December 29,1883.

To all whom it may concern.-

Be it known that we, ELBRIDGE F. BARNES and LORENZO O. STRIOKLAND,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inPipe-Gutters; and we do declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, which form a part of this specification.

Our invention relates to an improvement in that class of outsidepipe-cutters in which the bearing of the operating-screw is madeindependent of and. offsets from the frame of the cutter, the objectbeing to strengthen, simplify, and cheapen cutters of this class.

WVith these objects in view, our invention consists in providing thebearing of the operating-screw of the cutter with a lateral extension orshank, and the frame of the cutter with a transverse slot extending fromits front to its rear face, the shank of the bearing fitting into theslot in the frame.

Our invention further consists in providing the bearing of theoperating-screw of the cutter with a lateral extension or shank and witha shoulder, and the frame of the cutter with a transverse slot extendingfrom its front to its rear face, the shank of the bearing fitting intothe slot in the frame, and the shoulder thereof bearing against thefront face of the same at a point without the slot.

In the accompanying drawings, Figure 1 is a view in side elevation of apipe-cutter embodying our invention, and Fig. 2 is a similar detachedview of the bearing thereof.

Our invention consists, essentially, in pro viding the bearing F of theoperating-screw E with a lateral extension or shank, I, and the frame Kof the cutter with a transverse slot, l

as it approaches the rear face of the frame. Thisis to permit the outerend of the shank of the bearing to be upset into the slot, if de-.

(No model.)

sired to permanently secure the bearing to the frame.

In virtue of the construction described, the outward pressure which thescrew exerts upon the bearing is opposed by the resistance afforded bythe bearing of the whole length of the shank against the walls of theslot, and by the bearing of the shoulder upon the front face of theframe at a point thereon without the slot, whereby the shank isre-enforced in the direct line of the pressure. By this construction thecutter is made equal in effective strength so far as the bearing of theoperating-screw is concerned to a cutter having the said bearing castwith the frame. The parts require no fitting, and are readily puttogether, and as easily taken apart if it becomes necessary to repairthe cutter. If the bearing works loose under the pressure of the screw,it may be tightened by a blow upon its outer face.

\Ve are aware that it is not new to make an offsetting bearing for theoperating-screw of a pipe-cutter independent of the frame thereof, andhence we do not broadly claim such a construction, but limit ourselvesto the specific construction herein shown and described.

Vhat we claim as new and desire to secure by Letters Patent, is

1. An outside pipe-cutter having the bearing of its operating-screwprovided with a lateral extension or shank, which fits into a transverseslot extending from the front to the. rear face of thefraine of thecutter, substantially as set forth.

2. An outside pipe-cutter having the bearing of its operating-screwprovided with a lateral extension or shank and with a shoulder, theformer fitting into a transverse slot extending from the front to therear face of the frame of the cutter, and the latter. having bearingupon the front face of the same at a point without the slot,substantiallyas set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
